The Brief
What you'll do, and what you'll demonstrate.
Build and audit a 30-day readmission risk model on de-identified EHR data with calibration and fairness reported alongside discrimination.
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Apply ML to a real EHR-derived clinical-risk prediction problem
- Calibrate clinical-grade classifiers and report ECE alongside AUROC
- Audit subgroup performance gaps and reason about clinical equity
- Produce a model card that survives clinical review
